ethics

Don't make misrepresentations to anyone you deal with. If you believe the other person may have misunderstood you, correct any misunderstanding you find exists. Honesty is integral to ethical behavior, and trustworthiness is essential for good, lasting relationships.

. . . there's nothing of any importance in life - except how well you do your work. Nothing. Only that. Whatever else you are, will come from that. It's the only measure of human value. All the codes of ethics they'll try to ram down your throat are just so much paper money put out by swindlers to fleece people of their virtues. The code of competence is the only system of morality that's on a gold standard

A man's ethical behavior should be based effectually on sympathy, education, and social ties; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

Albert Einstein (1879 - 1955)
